While CCP does not endorse connecting to the server or web sites using a VPN or Proxy, the use of such services is not strictly forbidden. However this can cause problems such as updating the client. It is also possible that the user may connect via an IP address that has a bad history with us.
Should the use of the aforementioned services result in the account being suspended due to suspicious connection history, or preemptive security measures, please contact Customer Support via Support Tickets
Ultimately, it is recommended that users avoid the use of such services unless absolutely necessary and that the user does so at their own discretion while being aware of the potential risks associated with doing so.
